To all whom 'tt may concern:

Be it known that we, AnBEnT ERNEST IvEsoN, manufacturer, resid-ing at The lflellies, Gainsborough, in the county of Lincoln, England, and ARomBaLD RALPH WILSON, chemist, residing at Silver-lea,

:Portland Villas, Hove,` Brighton, in the -face, upon which the substances are deposited in I a layer, the deposition and ,removal of the layer taking place constantly. This invention is an improvement upon the former patent of A. R. Wilson assigned to A. E. I veson, dated April 25,

In carrying out our invention, we employ a tank for receiving fatty substances,

m which -one end or wall of the tank is 'formed by a moving surface, such as an endless carrier, or a drum or cylinder, means being used for cooling the interior of the carrier or cylinder and removing the layer of fatty substances deposited thereon. 'lhe tank is provided with means for heating the substances therein to keep them Huid, andl means for keepin the substances in said tank at substantial y a constant level.

With the objects stated in view, our invention -f consists the construction and combinations of parts as hereinafter de- ,.scribed and claimed.

In the accompanying drawings-Figure 1 represents an end view of one form of our the tank apparatus.' Fig. 2 represents a side view t ereof, Fig. 3 is a top plan view of a part of one of the scraping knives. Figli is a side view of a modification in which a cylinder is used. Fig. 5 is a front view of the same, and Fig." 6 is a rear view of the same.

` f A represents an endless band or carrier, which passes around two rollers C and D, and forms one slde of a reservolr or tank E, in which the fat to be vcooled is placed.

-Fis a Aipe for suppl ing melted fat to the supp y A a. oat valve G, so t at the level of the fat in the tank E is kept practically constant'.

eing governed by To prevent solidication, the fatty. substearn pipe H.

K represents a water tank, from which .water may be pumped through the pipe L into the pipes L1- and L1, which are situated inside the endless carrier or band A near the top thereof, and are perforated to discharge jets of water on the inside of the endless carrier A, to cool said carrier. M represents weighted knives, held up against the surface of the carrierA, which is prefv erably made' of sheet metal. These knives or .Scrapers have' indented edges, as shown in Fi 3, and are preferably arranged so that t e teethof the two knives will break joints, thus insuring` that all the fat collected on the endless carrier A is scraped oi.

N represents a roller located inside the endless carrierV A, for keeping said carrierl E, so that the liquid in said tank will not leak out around the ed es of the carrier, and O is a shield or screen ocated over the roller N, so that the water from the pipe L1 will will not cool the fat in said tank.

P lis a roller fitted with longitudinal knives s'o arranged as to cut the fat deposited on the endless carrier A into sections of any desired size, so that the fat may be easily scraped from the carrier A. The endless carrier A is moved by any suitable means, such as a belt, not shown, passing over the pulley B on the shaft of the roller C, said shaft beingy supported in brackets B1, the shaft of the pulley D being similarly supported in overhead brackets.

- In the modification shown in Figs. 4, 5 and 6, instead of the endless carrier A, a revolving cylinder is used, preferably made -'of meta. In this modification, A1 reresents a cylinder, and E1 the tank for holding the fat, said-tank having one of its sides cut away in a curve, so as to exactly t against the periphery of the cylinder A1. This cylinder 1s revolved by means of a wormB", vengaging a circular rack B2 on the shaft of the cylinder. L? and L* represent pipes for Adelivering water to the cylinder to cool its outsi e. P1 and P2 represent axles upon serve to cut up the fat deposited on the surface of the cylinder A1 into stuares, the knives P running longitudina y of the tightly pressed against the edges of the tank4 stances in the tank E are heated by the' be ydeflected away from the tank so that it e whi ,fknives 'P8 and 'P4 are carried, which eling belt M2.

The operation is evident from the foregoing description.

We claiml. An apparatus for cooling melted fatty substances, comprising a tank, means for heating the contents-oit' said tank, means' for maintaining the material under treatment at a constant level in said tank, a movable collecting medium, forming one of the Walls of said tank, means for cooling said medium,` means for subdividing the material collected on said medium, and vmeans for removing said collected material from said medium, substantially as described.

2. An apparatus for cooling melted fatty l I; substances, consisting of a tank, a traveling endless belt forming one Wall of said tank,

means located inside of said belt for cooling the same, devices for preventing the cooling medium from striking that part of the belt which-is adjacent to the tank, andv means for removing from said belt the material collected thereon, l,substantially as described.

An apparatus for cooling melted fatty substances, comprising a tank, means for heating the contents of said tank, means for maintaining the liquid at a` constant level in said tank, a traveling endless belt forming one of the Walls of said tank, means located insidel of said belt for cooling the same, devices for preventing the cooling medium from'striking that part of the belt which is adjacent to said tank, and means for removing from said belt the material collected thereon, substantially as described.

In witness whereof lWe have hereunto set our hands in presence of two Witnesses.
